Hi!

First time this happened in a project.

Initial processing seems to work great.

Quality Report seems fine too:

BUT big black hole in the Densified Point Cloud and therefore of course a blurry Ortho und DSM with hole.

Hi @Phil,

Thanks for your quality report.

My best guess is that your point cloud show these holes because there is lack of matching:

As you can see it here in many areas there are not connections/matching between the different cameras which results in many blocks (6 in your case).

I would try with these processing options:

Step1
Image scale on 1/2
Rematch “Yes”

Step2
Minimum number of matches on 2

This should already improve your point cloud.
Let me know if it worked.
Best
